Are the locks from the threading module interchangeable with those from the multiprocessing module?
You can typically use the two interchangeably, but you need to cognizant of the differences. For example, multiprocessing.Event is backed by a named semaphore, which is sensitive to the platform under the application.
Multiprocessing.Lock is backed by Multiprocessing.SemLock – so it needs named semaphores. In essence, you can use them interchangeably, but using multiprocessing’s locks introduces some platform requirements on the application (namely, it doesn’t run on BSD :))
